drm/amd/display: Enable otg synchronization logic for DCN321

[Why]
Tiled display cannot synchronize properly after S3.
The fix for commit 5f0c7491 ("drm/amd/display: Fix for otg
synchronization logic") is not enable in DCN321, which causes
the otg is excluded from synchronization.

[How]
Enable otg synchronization logic in dcn321.
